Impressed! *by on Reviewed in the United Kingdom 22 August 2025* Honestly amazing. My stomach was bloated for quite some time. I had on and off heartburn. Just generally felt rubbish. I bought these because of some of the reviews. They were amazing. I think I had gas stick in my stomach as my tummy was bloated up 2 clothes sizes. By the end of the week, the difference was amazing. I do still have the on and off heartburn but my stomach issue has been sorted. Will take this every 6 weeks to keep on top of everything or just keep a box on stand by.There is practically no flavour at all, a bit like potato starch. Drank it to problem. It doesn't always dissolve but it does work, so not fussed about that really. 5 stars for sure. I lost 2 kgs but unsure if it was to do with stored gas etc but was pleased anyway. Tgat was 6 weeks ago and gas stayed off. My friend tried it for meno belly and was also pleasantly surprised after telling me it was probably rubbish. Shebus very happy. I think the stomach needs a prebiotic/prebiotic from time to time to align it.If in doubt, definitely give it a go. ### ⭐⭐⭐⭐⭐ Brilliant product which works *by on Reviewed in the United Kingdom 15 February 2026* Brilliant product. I have gallstones so I deal with a lot of bloating, after a massive weight loss last year my stomach is one area of my body I’m most self conscious about and I was struggling with the area of my body I’m most self conscious about sticking out so I thought I’d try these. As I’m only on day 2 it’s still early days but i definitely feel less bloated after meals I’ve noticed, will see how I get on with the rest of the week but now considering taking these daily. ### ⭐⭐⭐⭐⭐ A miracle *by on Reviewed in the United Kingdom 4 December 2018* This is obviously a product which works for some but not for others. About 5 years ago, for no obvious reason my waist shot up by several inches and coping with things like waistbands and tights was nigh impossible. Two or three months ago a dietician immediately diagnosed 'bloating' and suggested I try One Week Flat. The result was astonishing. Within that first week I was back to normal and able once again to get into some of my own clothes which I was close to discarding. And tights are no longer a problem. I am using it one week on, two weeks off. I am unaware of any side effects.But it is important to acknowledge that it really doesn't work for everybody. I would just say, if you have a bloating problem try it. ## Frequently Bought Together - Optibac Probiotics One Week Flat - Vegan Digestive Probiotic Supplement Suitable for Bloating with 5 Billion Bacterial Cultures - 4 Week Supply - 28 Powder sachets - Optibac Probiotics Every Day - Digestive Probiotic Supplement with 5 Billion Bacterial Cultures & FOS Fibres - 30 Capsules - Optibac Probiotics Bifido & Fibre - Vegan Digestive Probiotic Supplement with FOS Fibre to Maintain Regularity & 25 Billion Bacterial Cultures - 30 Sachets --- ## Why Shop on Desertcart? - 🛒 **Trusted by 1.3+ Million Shoppers** — Serving international shoppers since 2016 - 🌍 **Shop Globally** — Access 737+ million products across 21 categories - 💰 **No Hidden Fees** — All customs, duties, and taxes included in the price - 🔄 **15-Day Free Returns** — Hassle-free returns (30 days for PRO members) - 🔒 **Secure Payments** — Trusted payment options with buyer protection - ⭐ **TrustPilot Rated 4.5/5** — Based on 8,000+ happy customer reviews **Shop now:** [https://www.desertcart.ec/products/48838525-one-week-flat-vegan-digestive-supplement-4-wk-supply-28](https://www.desertcart.ec/products/48838525-one-week-flat-vegan-digestive-supplement-4-wk-supply-28) --- *Product available on Desertcart Ecuador* *Store origin: EC* *Last updated: 2026-09-14*
